Thanks Sam, still a lot to add, plus tweaks of this and that.

No sign of Herb.....

I have this wild and wooly theory,
A certain Ol' Eagle's still in his aerie,
There's nary a peep
Is he still asleep,
Will he emerge looking ruffled and bleary?

Cheers Bazza :rolleyes:

The nose angle shot was chosen carefully, the boiler texture has been snookered by TS, it's needs more dithering to get rid of the layered look. It's just one of the things we modelers have to put up with, you tweak the texture until you get it looking good. :rolleyes:

Dithered boiler texture....horrible, but needs must! :rolleyes:

Something is amiss. As good as it has looked in the renders, it doesn't look right in the sim.



It's too narrow. Way too narrow. And too tall. The boiler sits too high. Notice on the prototype the way the cylinders are out far beyond the ends of the ties but the model's cylinders barely clear the ends of the ties. Notice too the way the toolbox covers the lower part of the smokebox on the real one and is below it on the model. Cylinder saddle can barely be seen in the proto. high and prominent in the model.

In the overhead shot the counterweights and the outside of the trailing truck are virtually even with the rail. Those counterweights should be 18" outside of the rails. Pilot beam is too narrow. Pilot cage is too narrow and too tall. Stack is too narrow.

Any one of these things would go unnoticed. All together and she doesn't look right at all. Hate to be the bearer of sad news but she needs to beef up laterally - a lot!

This is what needs to happen:

Hmmm, what you are seeing is the difference between a computerised rendered view and a photograph made through a lens...with all the distortions that involves,I assure you the model conforms to the plan dimensions in all respects, except the smokebox door is still a bit too big, I've already tweaked it once, so I guess it's back to the drawingboard on that.

Also, my screen resoluton may differ from yours, that can have quite an effect too, so other than hit the bugger a few times with a hammer I dunno if the look can be improved.

The golden rule, render vs photograph, no contest, add differing screens resolutions and other screen settings, and you can see there are variations in personal perceptions of proportion over which I have no control.

I will say that in the past I have also experienced the perception that a model made from a plan, with dimensions, didn't look 'right' in the renders/sim compared to photographs - and I have been guilty of tweaking the shape dimension to 'compensate', however, the K27 has gone well past the stage where major tweaks can be made and in this case I would not wish to anyway.

Another thing to consider is at rail level the middle of the boiler is approximately six feet high, I doubt there are many photographs of locomotives taken with the lens at that height, anything under, over, or at other angles leads to distortion.

Here are two screenshots taken with the same altered sim camview, equivalent to altering the focal length to approximate the film camera lens.





Compare these with the first screenshot at the begining of this thread.

Cheers Bazza

PS I also altered the height of my screen which was too high, it was a bit out in proportion to the width for my CRT screen for the screen res.

You may be right. She still looks a bit to narrow and not "hunkered down" enough. Adding the valve gear might alter that perception as well, with all that machinery flailing around.

You point out something that is also true in the model world. We look at our models from a totally different perspective than we do the prototype - usually too high to be a realistic view. Models sometimes don't look right from those angles because the photos we have of the real thing were never taken from that same perspective. Railfan photographers seldom had the advantage of helicopter useage! :rolleyes:

[captain_bazza]

and not "hunkered down" enough

Yeah, that's the effect seen in photos, I suspect reality is/was different. Adding the missing detail might just change the appearance, too, it usually does. Like I said, I took particular care to use the original specs, more so than usual. I tried to give the boiler texture a graduated lighting effect, so the bottom half looks like shadow. Who knows, we haven't got to the release version yet.
